Answer:
x=4
Step-by-step explanation:
We can find the length of RT by using the Pythagorean theorem
sin theta = opposite side/ hypotenuse
sin 60 = 2 sqrt(3)/ RT
Multiply each side by RT
RT sin 60 = 2 sqrt(3)
Divide by sin 60
RT = 2 sqrt(3)/ sin 60
RT = 4
Then
tan theta = opposite side/ adjacent side
tan 45 = x/RT
tan 45 = x/4
4 tan 45 = x
4 = x

Answer:
The answer to your question is: third option is correct
Step-by-step explanation:
Data
F (5, -1)
directrix y = 1
Then, after getting the graph, the vertix = (5, 0)
and p = 1
Formula
(x - h) ² = -4p(y - k)
(x - 5)² = -4(1)(y - 0)
(x - 5)² = -4y
y = (x - 5)² / -4
Answer:
Step-by-step explanation:
A. False. The probability of drawing a green marble twice is even smaller (It may be true though depending on what the question is asking, if it is asking the chance of drawing a green marble second is the same as the 1st chance, then yes it is True.
B.False
C. False
D.True, 1/3*1/3 (Simplified version of 6/18*6/18) is 1/9
E. False (Although this may be true, again depending on the type of question)
F. False
Answer:
Step-by-step explanation:
Let f(x) be the 3rd degree polynomial function.
The roots of this function are:
x=-2, x=-1 and x=3.
The factored form is:
This equation passes through (2,12)
This implies that;
The polynomial function is
